HEATER FOR, STOCK-:WATERING TANKS.

SPECIFICATION forming part of Letters Patent No. 428,702, dated May 27,1890.

I Application filed geptember 28, 1888. Serial No. 286,685. (No model.)

T0 or whom it mag concern Be it known that I, OLIVER GUY STOWELL, acitizen of the United States, residing at Delavan, in the county ofIValworth and State of Wisconsin, have invented a new and usefulImprovement in Heaters for Stock- VVatering Tanks, of which thefollowing is a specification.

My invention relates to improvements in heaters for stock-wateringtanks, the object being to provide a simple and inexpensive device bythe use of which the'water in the tank may be maintained at a uniformtemperature and prevented from freezing in cold weather, so that therewill always be a supply of water for the stock having the propertemperature. This object I accomplish by the use of the device shown inthe accompanying drawings; and the invention consists in certain novelfeatures of the same, to be hereinafter first fully described, and thenpointed out in the claim.

In the drawings referred to, Figure 1 is a perspective view of a tankprovided with my improvements. Fig. 2 is a vertical longitndinal sectionof the heater. Fig. 3 is a transverse vertical section on the line 00 0cof Fig. 2. Fig. 4 is a detail view showing the detachable head-plate.Fig. 5 is a detail perspgctive view of the adjustable knee or standarReferring to the drawings by letter, A designates a water-tank of anydesired size and shape, preferably, however, of an oblong rectangularform, and provided with a cover B, having a door (3. The cover may, ifdesired, be dispensed with; but I prefer to use it, as the water isthereby kept free from impurities, while at the same time the stock haveready access to it through the door 0, which can be opened for thatpurpose. The front end of the tank is provided with an opening D,throughwhich one end of the heater projects, as clearly shown. The saidheater consists of a cylindrical casting, as shown, having'its rear endprovided with a tapered extension E, having an annular flange F at itsextremity. The front end of the casting is provided with an annularflange G, which is adapted to rest against the front end of the tank, asshown. On the outer side or face of is pivoted a door I, provided with adamper J, and having a projection K,forming alatch adapted to engage ahook L projecting from the flange G.

On the inner side of the front end of the tank I provide a ring M,through which and the flange G, I insert the securing-bolts N, a packingO, of asbestus or similar material,

i being arranged between the flange and the end of the tank to form awater-tight joint.

P designates the grate, consisting of a casting having a series ofparallel longitudinal bars Q, connected at their ends by the crossbarsR. The outer sides of the outer longitudinal bars are curved, as shownin Fig. 3, to correspond with the inner convex surface of the heater,against which they impinge, so that the grate will be supported withoutthe use of bolts, feet, or other devices, as will be readily understoodupon reference to Fig. 3.

To the tapered extension at the rear end of the heater I secure the endof the smoke and heat flue S, which extends longitudinally through thetank to near the rear end of the same, where it is given an upward turnand extends through the roof or cover of the tank, as shown. The frontend of the smoke and heat flue is provided with an annular flange T,through which and the annular flange on the rear end of the heater Ipass securingbolts, as shown, to secure the fine to the heater, packingbeing arranged between the flanges to form a water-tight joint. Thesmoke and heat flue is made in sections U, connected together by meansof the bolts passed through flanges 011 the ends of the sections, asshown, the said flue being thus made readily adjustable to the size ofthe tank. If so desired, the sections may be secured together byscrewthread connections instead of the flanges and bolt, as will bereadily understood.

At the rear end of the heat and smoke flue, just beneath the verticalbranch V thereof, I provide a standard or knee IV, which is composed oftwo members adjustably secured together by means of a slot-and-boltconnection, the upper member being rigidly secured to the flue and thelower member being rigidly secured to the floor or bottom of the tank.

this flange I form a pair of lugs H, to which By this construction I amenabled to quickly adjust the rear end of the flue to the height of theheater, so as to secure the most perfect draft.

At a proper point of the height of the ver tical branch of the heaterand smoke-flue I provide the same with a collar X, having an annularflange Y, through which and the cover of the tank fastening-bolts arepassed to secure the flue firmly in place. Near the upper end of thevertical branch of the flue I provide a tilting damper or valve Z, bymeans of which the draft can be regulated.

a designates a removable head-plate of the same diameter as the flangeG, and having a series of perforations Z) near its edge.

In practice the heater will be removed from the tank in warm weather,and this headerplate is secured over the opening in the tank, thuspermitting the tank to be filled with water and at the same timepreventing the excessive and injurious rusting of the heater. The heatercan be easily removed from the tank, as there are no projections on itsouter surface, and its front edge extends through the opening in thefront end of the tank, the flange G resting against the outer side ofthe end of the tank, so that the heater can be drawn through the saidopening.

In practice the tank is filled with water and a fire kindled on thegrate in the heater in the usual manner, the draft being regulated bythe dampers in the door and the rear end of the heat and smoke flue. Thefire raises the temperature of the heater, which in turn radiates theheat through the water, keeping the same at a uniform temperature. Theheat and products of combustion pass from the heater through the flueleading therefrom, raising the temperature of the same, which in turnradiates heat through the water, so that the entire body of water willbe warmed.

It will be seen from the foregoing description that I have provided avery simple and efficient device by the use of which a constant supplyof water will be provided for the stock and maintained at a propertemperature to be drunk in quantities without any deleterious effect.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

The combination, with a stock-watering tank having a permanent cover anda hinged lid and provided with an opening at its front end, of aremovable heating device comprising a cylindrical easing tapering orcontracted at its rear end and having an annular flange at its frontend, an annular ring encircling said cylindrical casing and hearingagainst the inner side of the front end of the tank through the openingin which the heater-casing is inserted, bolts eonnecting said ringdetachably with the flange of the heater-casing and extending throughthe wall of the tank or trough, a door hinged to the flange at the frontend of the heatercasing, and a smoke-flue composed of sections connecteddetachably together and to the tapering rear end of the heater-casingand extending upwardly through the permanent cover of the tank,substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto at'fixedmy signature in presence of two witnesses.
